I just want to enter the value at runtime which is coming from the serial port donot have any idea about any other object

show these portions of your code
1. how you create your serial port reader
2. where you get the text from the serial port and attempt to assign to the textbox's Text property.

Serial Port Declaration :
private SerialPort comport = new SerialPort();
reponse from com port : string response = comport.ReadExisting()
Changing the value : textbox1.text = response.Substring(0, 1)

There's nothing using threading in the code you've posted. I assume you're using a thread to read the port, is your serial port declaration in there?
BTW, there's a simple example on MSDN[^] - it might be worth comparing to your code.

I guess you're setting the text from within the comport_DataReceived event handler, which the SerialProt object calls from another thread. Either you read up on threading, or you don't use the event but put a timer onto your form (or control) and poll the com port from the timer's Tick event.

Thanks,I had get the solution for my problem I had removed the comport_DataReceived from the event handler and now I am doing it with Timer now i am able to change the text box value at run time.
Thanks again

Is this what you mean?
System.Net.Dns.GetHostByName( "www..." );
edit: apparently GetHostByName is obsolete - use GetHostEntry now

Thanks! I needed something as simple but I still cant see the ip address!!
I tried
public static string GetWebsiteIP(string websiteName)
{
IPHostEntry host;
string strIP = String.Empty;
host = Dns.GetHostEntry(websiteName);
foreach (IPAddress ip in host.AddressList)
strIP += ip.ToString();
return strIP;
}
But I still get the website name I pass 
GetWebsiteIP("www.codeproject.com");

Funny! Ok, it works now, maybe I needed to clean the solution and rebuild..
Thanks for your help guys!

Just tried it and it works for me
Also, a domain name can map to multiple IP addresses, so you might want to return a string[], or maybe just pick the first one?

Hi mister,
I have an Winforms app (Client) and Web app + WCF Services + Windows Services (Server). In server, I have installed SQL SERVER 2000.
Now, I want create a installer (MSI.exe or another Winforms app) to create a database, perhaps user, tables, stored procedures, .. Only the user introduces name of database, server, and if has Windows authentication; if not Windows authentication, I need user and password.
I have several scripts SQL, that I need execute too. If I use isql command I have problmes with codification because my scripts sql have Spanish characters. I tested with using ANSI and UTF-8 encoding for scripts .sql files, but didn't work.
Finally, how I can create this installer ? is it better MSI ?? or can I create an WinForms app ??
Any sample will be very very grateful.
Thanks in advance.
AE

hi
how can i fix this problem in my connection string ?
LocalConnection = new SqlConnection("data source=localhost;database=Alarms;Integrated Security=True");
it will fixed when i substitute "localhost" with ".\\sqlexpress"
i want to work with sqlServer 2005 not sqlexpress
the error is:
An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the fact that
under the default settings SQL Server does not allow remote connections.
(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
